Risk levelMedium

0–100, higher is better. How it is calculated

The Centre national de la recherche scientifique (CNRS) is a leading French governmental research organization active across all scientific disciplines. The website reflects a mature digital presence with comprehensive scientific content, innovation initiatives, and societal challenges addressed. The organization targets researchers, academics, enterprises, and the general public interested in science and innovation. Technically, the site is built on Drupal 10, uses Matomo for analytics, and implements a consent management platform (Axeptio) for GDPR compliance. Security posture is solid with HTTPS and cookie consent, though some security headers and explicit incident response contacts are missing. The WHOIS data is unavailable, likely due to registry privacy policies, but the website's branding and external references strongly support legitimacy. Overall, the site is professional, trustworthy, and well-optimized for users.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

5 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Facebook, Twitter, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

CNRS holds a dominant position in French and global scientific research, funded primarily by the government and partnerships. Its business model focuses on fundamental research, innovation, and collaboration with enterprises and international bodies. The website highlights key services such as research dissemination, innovation protection, and societal challenges. The organization maintains a broad partnership ecosystem including its foundation, innovation branch, and alumni network. Growth indicators include active news, multimedia content, and engagement across multiple social media platforms. The digital presence supports its mission and outreach effectively.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, cookie consent mechanisms, and no visible sensitive data exposure. However, it lacks explicit security policies, vulnerability disclosure pages, and incident response contact information, which are important for transparency and trust. The absence of security headers like Content-Security-Policy or X-Frame-Options suggests room for improvement. No vulnerable libraries or scripts were detected. Overall, the security posture is adequate for a public institutional website but could be enhanced to meet best practices and compliance standards fully.

Recommendations

  1. Implement and publish a dedicated security policy and vulnerability disclosure page.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Provide clear incident response contact information, including security or abuse email addresses.
  4. Conduct regular audits of third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Improve accessibility compliance to meet recognized standards and enhance user experience for all visitors.

Technical notes

Notes

The website uses Drupal 10 CMS, indicating a modern and maintainable platform. It integrates Matomo analytics for privacy-respecting user tracking and Axeptio for cookie consent management, reflecting GDPR compliance. The presence of MathJax supports scientific content rendering. Performance is moderate with good mobile optimization and SEO practices. The site uses multiple external domains for content delivery and multimedia. No hosting provider details were found in the HTML. Technical risks are minimal but could be reduced by adding security headers and improving accessibility. Overall, the technical infrastructure supports the organization's mission effectively.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
